ECG Introduction 2020/11/30 4/26 NDT & NBMIS LAB

ECG Introduction A typical ECG signal profile with the timing of components defined Baseline 缺血—tall or inverted T wave (infarct), ST segment may be depressed (angina) 損傷—elevated ST segment, T wave may invert 梗塞 (急性)—abnormal Q wave, ST segment may be elevated and T wave may be inverted 梗塞 (時間不知）—abnormal Q wave, ST segment and T wave returned to normal 2020/11/30 5/26 NDT & NBMIS LAB
